| Product Description Sirenza Microdevices NGA-589 is a high performance InGaP/ GaAs HBT MMIC Amplifier. A Darlington configuration designed with InGaP process technology provides broadband performance up to 5.5 GHz with excellent thermal perfomance. The heterojunction increases breakdown voltage and minimizes leakage current between junctions. Cancellation of emitter junction non-linearities results in higher suppression of intermodulation products. At 850 Mhz and 80mA , the NGA589 typically provides +39 dBm output IP3, 20 dB of gain, and +19 dBm of 1dB compressed power using a single positive voltage supply. Only 2 DC-blocking capacitors, a bias resistor and an optional RF choke are required for operation.

Solder the copper pad on the backside of the device package to the ground plane. 2. Use a large ground pad area with many plated through-holes as shown. 3. We recommend 1 or 2 ounce copper. Measurement for this data sheet were made on a 31 mil thick FR-4 board with 1 ounce copper on both sides. LC CD CB CB Pin # Function RF IN Description RF input pin. This pin requires the use of an external DC blocking capacitor chosen for the frequency of operation. Connection to ground. Use via holes for best performance to reduce lead inductance as close to ground leads as possible. Part Identification Marking The part will be marked with an N5 designator on the top surface of the package. 4 1 2, 4 GND N5 1 2 3 2 1 3 3 RF OUT/ RF output and bias pin. DC voltage is BIAS present on this pin, therefore a DC blocking capacitor is necessary for proper operation.
